GHG Scopes 1, 2 and 3 vs CBAM Direct and Indirect Emissions: Mapping the Two Systems for Indian Exporters

Navigating the Carbon Maze: GHG Scopes vs. CBAM Emissions for Indian Exporters

For Indian manufacturers exporting to the European Union, understanding the nuances of carbon accounting is no longer optional – it's a critical business imperative. The EU's Carbon Border Adjustment Mechanism (CBAM), established by Regulation (EU) 2023/956, introduces a new layer of complexity, demanding precise measurement and reporting of embedded emissions in imported goods. While many Indian companies are familiar with the Greenhouse Gas (GHG) Protocol's Scopes 1, 2, and 3 for corporate sustainability reporting, CBAM introduces its own definitions of "direct" and "indirect" emissions. This article aims to demystify these two frameworks, map their interconnections, and provide actionable guidance for Indian MSMEs and large exporters in sectors like steel, cement, aluminium, fertilisers, and hydrogen.

The stakes are high. Misinterpreting these definitions can lead to inaccurate reporting, higher CBAM liabilities (potentially increasing costs by 20-30% if default values are applied), and even penalties once the definitive phase begins in January 2026. For a steel plant in Jamshedpur or an aluminium smelter in Gujarat, getting this right means the difference between competitive advantage and significant financial burden.

Key Takeaways

• CBAM vs. GHG Protocol: While related, CBAM's "direct" and "indirect" emissions are specific subsets of the broader GHG Protocol Scopes 1, 2, and 3, tailored for product-level embedded emissions.
• Direct Emissions (CBAM): Primarily corresponds to GHG Scope 1 emissions from the production process of the CBAM good itself.
• Indirect Emissions (CBAM): Focuses specifically on electricity consumption (GHG Scope 2) during the production process of the CBAM good.
• Scope 3 Exclusion (Mostly): Most GHG Scope 3 emissions (e.g., upstream raw materials, transport) are generally excluded from CBAM calculations for the final CBAM good, with some crucial exceptions for specific precursors.
• Data is King: Accurate, granular data on fuel consumption, electricity usage, and production volumes at the facility level is paramount for minimizing CBAM costs.
• Indian Context: Indian utilities (MSEDCL, UGVCL, TANGEDCO) and their specific emission factors are crucial for calculating indirect emissions.
• 2026 Impact: The definitive phase starting January 2026 will introduce financial obligations, making precise emission calculations critical to avoid punitive default values.
• CarbonSettle's Role: CarbonSettle provides end-to-end CBAM compliance services, taking the entire burden off Indian exporters, from data collection to verified report generation.

What is the GHG Protocol and its Scopes (1, 2, 3)?

The Greenhouse Gas (GHG) Protocol is the most widely used international accounting standard for measuring and managing greenhouse gas emissions. It provides a comprehensive framework for companies and organizations to quantify and report their emissions across their entire value chain. The protocol categorizes emissions into three "Scopes":

Scope 1: Direct Emissions

These are emissions that occur from sources owned or controlled by the reporting company. Think of them as emissions directly from your factory's operations.

• Examples for an Indian manufacturer:
  • Combustion of fossil fuels in boilers, furnaces, and industrial processes (e.g., burning coal in a cement kiln in Pune, natural gas in a fertiliser plant in Gujarat).
  • Emissions from company-owned vehicles (e.g., trucks transporting goods from a Ludhiana steel mill).
  • Fugitive emissions from refrigerants, air conditioning, or industrial gases (e.g., methane leaks from a hydrogen production facility).
  • Process emissions from chemical reactions (e.g., CO2 released during clinker production in cement manufacturing).

Scope 2: Indirect Emissions from Purchased Energy

These are emissions from the generation of purchased electricity, steam, heating, and cooling consumed by the reporting company. While the emissions occur at the utility provider's facility, they are a direct consequence of the company's energy consumption.

• Examples for an Indian manufacturer:
  • Emissions associated with electricity purchased from the grid (e.g., from MSEDCL in Maharashtra, UGVCL in Gujarat, or TANGEDCO in Tamil Nadu) to power machinery, lighting, and other operations in your factory.
  • Emissions from purchased steam or heat used in industrial processes.

Scope 3: Other Indirect Emissions

These encompass all other indirect emissions that occur in a company's value chain, both upstream and downstream, that are not included in Scope 2. These are often the most challenging to quantify due to their breadth and reliance on third-party data.

• Examples for an Indian manufacturer:
  • Upstream: Emissions from the extraction, production, and transport of purchased raw materials (e.g., iron ore for steel, bauxite for aluminium, limestone for cement).
  • Upstream: Business travel, employee commuting.
  • Upstream: Waste generated in operations.
  • Downstream: Transportation and distribution of sold products.
  • Downstream: Use of sold products (e.g., emissions from a car manufactured using your steel).
  • Downstream: End-of-life treatment of sold products.

The GHG Protocol provides a holistic view of a company's carbon footprint, crucial for corporate sustainability reporting, setting reduction targets, and demonstrating environmental stewardship.

How Does CBAM Define "Direct" and "Indirect" Emissions?

The EU CBAM Regulation (Regulation (EU) 2023/956) has a much more specific and narrowly defined scope for emissions reporting, focusing solely on the embedded emissions within the imported CBAM goods themselves. It categorizes these emissions into "direct" and "indirect."

CBAM Direct Emissions

CBAM Direct Emissions are defined as the GHG emissions released during the production processes of the CBAM goods at the facility where they are manufactured. This definition closely aligns with, and is essentially a subset of, GHG Scope 1 emissions.

• Key Characteristics:
  • Facility-Specific: These are emissions occurring at the specific production facility (e.g., your factory in Ludhiana or Pune) where the CBAM good is produced.
  • Process-Related: They include emissions from the combustion of fuels (e.g., coal, natural gas, furnace oil) used in the production process and process emissions from chemical reactions inherent to the manufacturing of the CBAM good.
  • Examples for Indian Exporters:
    • CO2 emissions from the burning of coke and other fuels in a blast furnace for steel production.
    • CO2 emissions from the calcination of limestone in a cement kiln.
    • Emissions from the use of natural gas as a feedstock and fuel in ammonia (fertiliser) production.
    • Emissions from the anode effect in aluminium smelting.
    • Emissions from the steam methane reforming (SMR) process for hydrogen production.

CBAM Indirect Emissions

CBAM Indirect Emissions are specifically defined as the GHG emissions from the generation of electricity consumed during the production processes of the CBAM goods at the facility where they are manufactured. This definition is a very specific subset of GHG Scope 2 emissions.

• Key Characteristics:
  • Electricity Only: Unlike the broader Scope 2, CBAM indirect emissions are only concerned with electricity consumption. Emissions from purchased steam, heating, or cooling are generally not included here unless they are generated using electricity.
  • Facility-Specific: Like direct emissions, these are tied to the electricity consumed at the specific production facility.
  • Grid Emission Factors: Calculating these requires knowing the quantity of electricity consumed and the specific emission factor of the electricity grid from which it was sourced. For Indian exporters, this means using the grid emission factors for utilities like MSEDCL, UGVCL, or TANGEDCO, or specific supplier emission factors if renewable energy is purchased directly.
  • Examples for Indian Exporters:
    • Emissions from the electricity used to power rolling mills in a steel plant.
    • Emissions from electricity consumed by grinding mills and packaging units in a cement factory.
    • Emissions from the massive electricity consumption in aluminium electrolysis.
    • Emissions from electricity used for compressors and pumps in a fertiliser plant.
    • Emissions from electricity used in electrolysis for green hydrogen production.

Mapping GHG Scopes to CBAM Emissions: A Detailed Comparison

Understanding the overlap and distinctions between these two frameworks is crucial for accurate CBAM reporting.

The Critical Role of Precursors and Upstream Emissions

While CBAM largely excludes most Scope 3 emissions, there's a significant caveat for Indian exporters: emissions embedded in precursor materials that are themselves CBAM goods must be included.

For example:

• Steel: If you produce finished steel products (e.g., steel bars, coils) from purchased pig iron or slabs, the embedded emissions of that pig iron or slab (if it's a CBAM good) must be accounted for as part of your final product's CBAM emissions. This requires data from your upstream suppliers.
• Cement: If you produce cement from purchased clinker, the emissions embedded in that clinker are part of your cement's CBAM footprint.
• Aluminium: Primary aluminium production involves significant emissions. If you are importing secondary aluminium products, the emissions from the primary aluminium used to create the scrap (if relevant) or the remelting process are critical.

This means Indian exporters cannot simply ignore their supply chain; they must engage with their suppliers to obtain accurate emissions data for relevant precursor materials. This is where the complexity truly ramps up, requiring robust supplier engagement strategies.

Practical Steps for Indian Exporters: From Scopes to CBAM Compliance

For an Indian factory owner in Ludhiana producing steel pipes or a cement manufacturer in Gujarat, the immediate question is: "How do I translate this into actionable steps for CBAM compliance?"

Step 1: Identify Your CBAM Goods and HS/CN Codes

First, determine if your exported products fall under CBAM. The covered sectors are iron & steel, cement, aluminium, fertilisers, hydrogen, and electricity. Each product has a specific Combined Nomenclature (CN) code.

• Action: Cross-reference your product's Harmonized System (HS) code with the EU's CBAM CN code list. This is the foundational step. You can use resources like the CBAM CN code directory to verify.

Step 2: Map Your Production Process and Emission Sources

Create a detailed flow chart of your production process for each CBAM good. Identify all inputs (raw materials, fuels, electricity) and outputs.

• Action: For each CBAM good, list all direct fuel combustion sources (boilers, furnaces), process emissions (e.g., CO2 from calcination), and electricity consumption points. This directly feeds into identifying your CBAM Direct and Indirect emissions.

Step 3: Data Collection Strategy for CBAM Direct Emissions (GHG Scope 1)

This requires granular data on fuel consumption and process emissions.

• Fuel Consumption:
  • Data Needed: Type of fuel (coal, natural gas, furnace oil, petcoke), quantity consumed (tonnes, cubic meters, litres), and calorific value for each fuel used in the production of the CBAM good.
  • Source: Purchase invoices, fuel meters, production logs.
  • Example: A steel plant in Jamshedpur needs to track the exact amount of coking coal and natural gas used per tonne of steel produced.
• Process Emissions:
  • Data Needed: Quantity of raw materials undergoing chemical transformation (e.g., limestone for cement, iron ore for steel), and the relevant emission factors for these processes.
  • Source: Material balance calculations, industry-specific emission factors (e.g., IPCC guidelines, EU ETS benchmarks).
  • Example: A cement factory in Pune must track the amount of clinker produced and the CO2 released during its calcination.

Step 4: Data Collection Strategy for CBAM Indirect Emissions (GHG Scope 2 - Electricity Only)

This focuses solely on electricity consumption.

• Electricity Consumption:
  • Data Needed: Total electricity consumed (kWh or MWh) for the production of the CBAM good. If your facility produces multiple products, you'll need to allocate electricity consumption accurately.
  • Source: Electricity bills (e.g., from MSEDCL, UGVCL, TANGEDCO), sub-meters for specific production lines.
  • Emission Factor: The specific grid emission factor for your electricity supplier. If you have a Power Purchase Agreement (PPA) for renewable energy, you'll need the supplier-specific emission factor.
  • Example: An aluminium plant in Gujarat consumes vast amounts of electricity. They need to track this consumption per tonne of aluminium and apply the correct grid emission factor for UGVCL or their specific power provider.

Step 5: Engage Your Upstream Suppliers for Precursor Emissions (Relevant GHG Scope 3)

This is where CBAM extends its reach into your supply chain.

• Action: Identify all precursor materials that are themselves CBAM goods (e.g., pig iron, clinker, primary aluminium). Reach out to these suppliers in India or abroad and request their embedded emissions data.
• Challenge: Many Indian suppliers may not have this data readily available. This requires proactive engagement and potentially assisting them in their own data collection.
• Default Values: If supplier data is unavailable, EU default values will apply, which are typically much higher and will significantly increase your CBAM liability. For instance, using EU default values could increase your CBAM tax by 20-40% compared to actual, lower emissions.

Step 6: Calculation and Allocation

Once data is collected, the next step is to calculate the embedded emissions per tonne of your CBAM product.

• Direct Emissions: Sum up CO2 emissions from fuel combustion and process emissions, then divide by the quantity of the CBAM good produced.
• Indirect Emissions: Multiply electricity consumption by the relevant grid emission factor, then divide by the quantity of the CBAM good produced.
• Precursor Emissions: Add the embedded emissions from relevant precursor materials.
• Allocation: For facilities producing multiple products, accurate allocation of shared emissions (e.g., from a common boiler or shared electricity) is critical. This often involves using mass balance, energy balance, or economic allocation methods.

Step 7: Reporting and Verification

The collected and calculated data must be reported to the EU Commission. During the transitional period (until end 2025), quarterly reports are required. From January 2026, annual reports with financial obligations will commence, requiring verification by an accredited verifier.

• Action: Prepare your data in the required format (e.g., XML for EU submission). Ensure all calculations are transparent and auditable.
• Verification: Engage an accredited verifier to attest to the accuracy of your reported emissions.

2026 Regulatory Impact for Indian Exporters: The Definitive Phase

The transitional period (October 2023 - December 2025) is a learning phase, primarily focused on reporting without financial penalties. However, January 2026 marks the beginning of the definitive phase of CBAM, and this is where the financial implications become very real for Indian exporters.

From January 2026:

1. Financial Obligation: EU importers will be required to purchase and surrender CBAM certificates corresponding to the embedded emissions of the goods they import. The price of these certificates will be linked to the weekly average price of EU Emissions Trading System (ETS) allowances, currently fluctuating around €60-€80 per tonne of CO2e (approximately **₹5,400 - ₹7,2
